  • Infrared satellite rainfall monitoring: relationships between cloud towers, rainfall intensity, and lightning

    Infrared satellite precipitation estimation algorithms rely on relationships between cloud top properties and rainfall. This study is unique in comparing instantaneous (rather than average) precipitation distributions and lightning strikes to satellite-detected cloud tower attributes. Roughly 2/3 of cloud towers represented areas of strong updrafts rising out of the surrounding cloud mass. Half ...

  • The SESAMO early warning system for rainfall-triggered landslides

    The development of Web-based information systems coupled with advanced monitoring systems could prove to be extremely useful in landslide risk management and mitigation. A new frontier in the field of rainfall-triggered landslides (RTLs) lies in the real-time modelling of the relationship between rainfall and slope stability; this requires an intensive monitoring of some key parameters that ...

  • Towards a generic rainfall-runoff model for green roofs

    A simple conceptual model for green roof hydrological processes is shown to reproduce monitored data, both during a storm event, and over a longer continuous simulation period. The model comprises a substrate moisture storage component and a transient storage component. Storage within the substrate represents the roof's overall stormwater retention capacity (or initial losses). Following a storm ...

  • Application of IHACRES rainfall-runoff model to the Wadi Dhuliel arid catchment, Jordan

    With increasing stress on water resources in Jordan, application of rainfall-runoff models can be part of the solution to manage and sustain the water sector. In this paper, the metric conceptual IHACRES model is applied to the Wadi Dhuliel arid catchment, north-east Jordan. Rainfall-runoff data from 19 storm events during 1986 to 1992 have been used in this study. Flood estimation was performed ...

  • Predicting combined sewer overflows chamber depth using artificial neural networks with rainfall radar data

    Combined sewer overflows (CSOs) represent a common feature in combined urban drainage systems and are used to discharge excess water to the environment during heavy storms. To better understand the performance of CSOs, the UK water industry has installed a large number of monitoring systems that provide data for these assets. This paper presents research into the prediction of the hydraulic ...

  • The Effects of Rainfall on Escherichia coli and Total Coliform Levels at 15 Lake Superior Recreational Beaches

    Fifteen beaches along Lake Superior were monitored over the course of the 2003 and 2004 summer swimming seasons from mid-May through mid-September. Water samples were collected at these 15 beaches less than 24-h after a rainfall event of at least 6 mm. The effect of rainfall on bacterial concentrations along theWisconsin shores of Lake Superiorwas investigated.Water samples were collected at a ...

  • Drought analysis in southern Paraguay, Brazil and northern Argentina: regionalization, occurrence rate and rainfall thresholds

    The objective of the present study is to characterize the drought occurrences in a region comprising Paraguay, southern Brazil and northeastern Argentina. To recognize the drought occurrences the standardized precipitation index at the time-scales of 3 and 6 months was applied to the rainfall records from 1961 to 2011 at 51 rain gauges located in that region. After a drought regionalization ...

  • Rainfall and river flows are predictors for β-glucuronidase positive Escherichia coli accumulation in mussels and Pacific oysters from the Dart Estuary (England)

    Rainfall and river flows are environmental variables influencing the microbial status of bivalve mollusc harvesting areas. This study investigated spatial and temporal relationships between rainfall, river flows and concentrations of Escherichia coli in mussels (Mytilus spp.) and Pacific oysters (C. gigas) from three harvesting areas in the Dart Estuary over the ...

  • Grille Monitoring in Scottish Borders

    Hydro-Logic was appointed to supply 4 trash screen monitors to the Scottish Borders Council. They were installed to monitor the level upstream of the screens and to provide alarms when the level reached a set threshold. This alarm was to be used by the council to indicate a build up of debris in front of the screen that would have created a flood risk potential. The alarms are transmitted along ...

  • Cottingham Culvert Trash Screen monitoring

    East Riding of Yorkshire Council commissioned Hydro-Logic to install flood monitors in the village of Cottingham, near Kingston upon Hull. Residents in this area had been dramatically affected by the floods of June 2007. Extremely intense rainfall combined with already saturated land resulted in localised flooding which was made worse by the effects of easily blocked 'trash screens' at numerous ...

  • Water quality monitoring with hydrolab MS5

    Background The Škocjan caves are a unique natural phenomenon located in south western Slovenia and are preserved as the Škocjan Caves Park under UNESCO protection. One of the most famous network of underground caves in the world, they were formed by the flow of the Reka River as it bored tunnels through the region’s limestone geology. The river first disappears underground just outside the ...

  • Vancouver public library green roof monitoring project

    Introduction: Public Works and Government Services Canada (PWGSC) initiated this study to add to the pool of information on Best Management Practices (BMPs) and Low Impact Development (LID) methods. In June 2003, PWGSC partnered with Kerr Wood Leidal Associates Ltd. to conduct a year long monitoring project on the Vancouver Public Library green roof. The purpose of this project is to assess ...

  • Monitoring Flow Rate in a Channel to Minimize Water Pollution

    Recently a wastewater management district in Cleveland contacted CAS DataLoggers to supply an automated monitoring solution for their environmental project. In most cities, sanitary sewers and storm sewers were separate, so that storm water was diverted into a nearby lake. However, Cleveland had only one sewer available, so all of the flow went to the ...

  • Forest camera traps monitor world’s endangered species

    Hidden in some of the world’s most impenetrable forests, a network of cameras with inbuilt motion sensors are snapping animals in their tropical habitats. The photographs in this gallery were captured in forests in Africa, Asia and Latin America. They provide information on animal populations that are usually unseen by humans. With the help of local inhabitants, scientists from the TEAM ...

  • Tunnelling in Chalk: Groundwater monitoring and risk assessment

    Morgan Est is constructing a tunnel to carry high voltage electricity cables between two electrical substations.  The tunnel will mostly be excavated in Chalk, with some excavation occurring in the Thanet Sands. ESI was appointed as Morgan Est’s environmental consultant for the project and has managed liaison between Morgan Est, regulators and other stakeholders over the last four ...

  • Remote monitors track river restoration success

    The Norfolk Rivers Trust has installed a remote river monitoring station that has been tracking water quality and flow before and after river restoration work at an area of ecological importance on the River Nar. Rising in chalk hills to the east of the village of Tittleshall, the river flows south for 2.5 km until it reaches Mileham, then predominately west for 39.5 km through the villages of ...


  • Monitoring and validation of decentralised water and wastewater systems for increased uptake

    Decentralised water and wastewater systems are being implemented to meet growing demand for municipal services either in combination with centralised systems or as standalone systems. In Australia, there has been increased investment in decentralised water and wastewater systems in response to the capacity constraints of existing centralised systems, an extended period of below average rainfall, ...

  • Combining modeling and monitoring to study fecal contamination in a small rural catchment

    The present study sought to identify Escherichia coli sources in a small catchment and to use the agro-hydrological model soil and water assessment tool (SWAT) to estimate their impact on river water quality. The innovative aspects of this research are to assess the hourly variations of fecal contamination and to take these variations into account in the model to provide a better evaluation of ...
