Monitoring watershed health

Background Municipal water quality managers recognize the need for data that can be used to monitor and assess the impact of urbanization on the condition of natural watersheds. Storm events, in conjunction with the alteration of native landscape, building of roads and overuse of fertilizer, can contribute to excess nutrients, sediment and other pollutants in environmentally significant ...

Evaluating the success of phosphorus management from field to watershed

Received for publication January 30, 2008. Studies have demonstrated some P loss reduction following implementation of remedial strategies at field scales. However, there has been little coordinated evaluation of best management practices (BMPs) on a watershed scale to show where, when, and which work most effectively. Thus, it is still difficult to answer with a degree of certainty, critical ...

City of Santa Monica Airport Watershed Management Plan

ABSTRACT The City of Santa Monica implements best management practices (BMPs) to address urban stormwater runoff and uses a “hierarchy” of BMPs to prioritize implementation based on the principles of protecting public safety and the environment, maximizing environmental benefits, and minimizing costs. The hierarchy of BMPs includes the following (in order of priority): 1) harvesting, ...

Applying Integrated Watershed Management Techniques in Stevens Creek

ABSTRACTThe Stevens Creek Watershed located just east of Lincoln, Nebraska, will experience rapid growth pressures in the coming years, a trend that has the potential to adversely impact the region’s natural resources. To maintain a balance of economic growth opportunities and the protection of natural resources, the City of Lincoln and the Lower Platte South Natural Resource District embarked on ...

Watershed Project Presents Challenges

Dennis McAlpine, P. E., project engineer at Houston Engineering, Inc. (HEI) acknowledges he enjoys a professional challenge. He has one. And so do several other folks connected with a $3 million water management project to clean up lakes in the Rice Creek Watershed District (RCWD), as well as other projects. The district is in the north/northeast sector of the metropolitan area and includes parts ...

Managing the NYC Watershed WWTP Upgrade Program- “Re-tooling an Entire Watershed’s Wastewater Treatment Infrastructure”

New York City has the largest unfiltered surface water supply in the world. Within the 1,969 square miles tributary to the system's 19 reservoirs and three controlled lakes, are 106 non-City-owned permitted wastewater treatment plants, owned by a wide variety of private, public and municipal organizations. In order to avoid filtration of their 1.3 Billion gallon per day supply, New York City ...

Sizing mitigation wetlands in agricultural watersheds

In this study, we investigated use of microcosms to supplement field studies for establishing the size of wetlands required to mitigate nitrate pollution in agricultural watersheds. Wetlands investigated in this study were located in San Joaquin Valley (California, USA) and demonstrated mean nitrate-nitrogen mass removal efficiencies ranging between 10 and 34%. Mean areal nitrate removal ...

Comparison of different targeting methods for watershed management practices implementation in Taleghan dam watershed, Iran

Soil erosion and sediment control is important in watersheds with planned dam construction. For an efficient implementation of watershed management practices, identification of critical areas is vital. Many studies have made an effort to identify and prioritize critical sub-watersheds. But very limited studies have been conducted to rank sub-watersheds in terms of their sediment yield ...

Drought indices supporting drought management in transboundary watersheds subject to climate alterations

There is growing concern in Iraq about the inefficiency of reactive drought management practices. Corresponding actions are largely characterized as emergency-based responses that treat the symptoms of drought rather than consider the vulnerability components associated with impacts. The Diyala watershed shared between Iraq and Iran has been used as an example transboundary river basin marked ...

SWAT meta-modeling as support of the management scenario analysis in large watersheds

In the last two decades, numerous models and modeling techniques have been developed to simulate nonpoint source pollution effects. Most models simulate the hydrological, chemical, and physical processes involved in the entrainment and transport of sediment, nutrients, and pesticides. Very often these models require a distributed modeling approach and are limited in scope by the requirement of ...

Integrated water resources assessment and management in a small watershed – a geomorphic approach

Depleting water resources and increasing human demands on the available fresh water resources suggest the need and scope for integrated water resources assessment and management. Narava basin, a small watershed spread over 105 km2 with a khondalitic suite of rocks and gneisses of Archaean age in the north coastal region of Andhra Pradesh, India was studied to propose effective water resources ...

Feasibility of rural regeneration by cooperative watershed resources management in Japan

This study addresses multiple social issues in order to regenerate collapsing rural regions and realise environmentally friendly economic growth from a standpoint of watershed-based management. It is difficult for a single agricultural community to revitalise itself and therefore, such a community needs to seek cooperative management involving other regions and industrial sectors. In this case ...

Preliminary identification of watershed management strategies for the Houjing river in Taiwan

The Houjing River watershed is one of the three major river watersheds in the Kaohsiung City, Taiwan. Based on the recent water quality analysis, the Houjing River is heavily polluted. Both point and non-point source (NPS) pollutants are the major causes of the poor water quality in the Houjing River. Investigation results demonstrate that the main point pollution sources included municipal, ...

Watershed-level analysis of exceedance frequencies for different management strategies

Exceedance of water-quality standards is important in assessing water quality. The effectiveness of soil conservation Beneficial Management Practices (BMPs) should be measured according to the BMPs' impact on exceedance frequencies. However, estimating exceedance frequencies for different management scenarios with field measurements is practically impossible due to difficulties in obtaining ...

Balancing Wetland Regulation with Stormwater Management on a Watershed-Wide Basis: A Case Study.

Maryland reconciles rapid growth, water-quality goals, and habitat protection. In response to increasing regulatory authority over its water resources, the Maryland Department of the Environment (MDE) has combined various programs and processes into a 'one-stop shop' where various issues can be addressed in a uniform and consistent manner. As part of this process, onsite conditions are assessed, ...

Measuring the Effectiveness of Watershed-Based General Stormwater Permitting

ABSTRACTThe U.S. EPA and most water resources professionals advocate holistic and adaptive watershed management approaches to the protection and restoration of aquatic ecosystems by encouraging pollution control strategies that are developed through collaborative partnerships within a hydrologic boundary. This paper evaluates the effectiveness of the holistic adaptive management approach through ...

Input-output model based ecological risk assessment for ecological risk management of watersheds: a case study in the Taihu Lake watershed, China

To achieve advanced watershed ecological management, policy-makers have struggled to predict ecological impacts for a long time. As a process of ecosystem analysis, ecological risk assessment (ERA) has been widely adopted to analyse the possibility of adverse ecological effects. ERA has developed from considering only a few indicators in an area to multiple sources and receptors in large-scope ...

Development of SPAWM: selection program for available watershed models

A selection program for available watershed models (also known as SPAWM) was developed. Thirty-three commonly used watershed models were analyzed in depth and classified in accordance to their attributes. These attributes consist of: (1) land use; (2) event or continuous; (3) time steps; (4) water quality; (5) distributed or lumped; (6) subsurface; (7) overland sediment; and (8) best management ...
