  • Sediment Spill Monitoring from Dredging, using the SediMeter

    Strategies for sediment spill monitoring and siltation measurements. The SediMeter allows a gradual increase in the equipment investment as conditions merit, from a single stand-alone logger, to a real-time monitoring network in which all previously purchased equipment can be included. Sediment spill causing siltation gives rise to two separate environmental problems: A suspended sediment plume ...

  • Estimation of erosion rate in a small catchment of Loktak wetland, India, using lead-210 (210Pb) technique

    Loktak Lake, one of the largest freshwater wetlands in the northeastern India, is under severe pressure due to many reasons-the main being increased siltation from the degraded catchment area. In the present study Nuclear Technique [Lead-210 (210Pb) Technique] has been applied to estimate soil erosion rates in the catchment of the lake. The erosion rates of the various land uses in the catchment ...

  • Short‐term macroinvertebrate recruitment and sediment accumulation: A novel field chamber approach

    Stream‐deposited sediment is one of the major stressors affecting stream biota. Several methods exist to quantify stream sediment embeddedness, but they are relatively qualitative and operationally defined. The authors developed a short‐term in situ embeddedness chamber method to measure aquatic insect recruitment and associated sediment accumulation in a more quantitative, better replicated ...

  • Microbe-assisted phytoremediation approach for ecological restoration of zinc mine spoil dump

    Mining is one of the sectors that impacts air, water and soil pollution. The various environmental problems that are associated with mining activities are deforestation, removal of fertile topsoil, unstable slopes prone to sliding and erosion, siltation of water bodies due to wash off of mineral overburden dumps, air pollution due to discharge of dust and noise pollution. The most effective means ...

  • Water salinity investigation in the Sundarbans rivers in Bangladesh

    Bangladesh, through its complex network of river systems, drains an area of about 1.76 million km2 of the catchments of the Ganges, the Brahmaputra and the Meghna, of which only 7.5% lies in Bangladesh. The Sundarbans is situated in the Ganges catchment area, which is known as the single largest mangrove forest and unique ecosystem in the world. It has an area ...

  • In-stream bioreactor for agricultural nitrate treatment

    Nitrate from agricultural activity contributes to nutrient loading in surface water bodies such as the Mississippi River. This study demonstrates a novel in-stream bioreactor that uses carbonaceous solids (woodchips) to promote denitrification of agricultural drainage. The reactor (40 m3) was trenched into the bottom of an existing agricultural drainage ditch in southern Ontario (Avon site), and ...

  • Nakoma Brook flood & hydraulic analysis & engineering study Sloatsburg, New York

    Performed Hydrologic Studies and Hydraulic Engineering Investigations and Designs for the Nakoma Brook Watershed located in Western Rockland and Southeastern Orange Counties, encompassing over 8 square miles. The study area focus was in the Village of Sloatsburg, NY at the intersection of Route 17 and Eagle Valley Road. Flood Control analyses were conducted using USACOE's HEC-1 and HEC-2 computer ...

  • Living with the floods, not against them

    “Yes, we are illiterate sir, but we are engineers as far as our experience with water and rivers is concerned”, says Phushi Mahato, a villager in the Gosi Kandak floodplains in North-Bihar in India. As an outcome of water resource management that failed to understand the role of fluvial regimes in delta, Phushi and his fellow village members have now become vulnerable to floods ...

  • An Interview with Tilahun Amede: Improving Water Resource Management in the Nile Basin

    In October 2012, Nourishing the Planet’s Carol Dreibelbis spoke with Tilahun Amede of the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT). ICRISAT aims to empower people living in drylands around the world to overcome poverty, hunger, and a degraded environment through better agriculture. For the past several years, Dr. Amede ...

  • Expanding marine protected areas to restore fisheries

    After World War II, accelerating population growth and steadily rising incomes drove the demand for seafood upward at a record pace. At the same time, advances in fishing technologies, including huge refrigerated processing ships that enabled trawlers to exploit distant oceans, enabled fishers to respond to the growing world demand. In response, the oceanic fish catch climbed from 19 million tons ...

  • Wallingford solutions enable an integrated approach to modeling

    Of the many advantages to Wallingford Software’s InfoWorks suite of solutions, one that is particularly valued in today’s demanding modeling environment is their reputation as the gold standard for integration. The solutions allow one interface to answer a wide range of questions, rather than requiring a user to laboriously work through a range of modules or packages. Such key but separate ...
