This data note describes the Biscuit Brook and Neversink Reservoir watershed long-term monitoring that includes: 1) stream discharge, (1983–2020 for 1937–2020 watershed), 2) water chemistry, 1983–2020, at 4 stations, 3) fish survey from 16 locations in 1990–2019, 4) soil chemistry 2 headwater sub-watersheds, 1993–2012 5) periodic sampling 364 throughout watershed, 1983–2020. The Catskill Mounta...

Kabani river is a 7 order stream with a basin area of 1647 km. There are 4 sixth order and11 fifth order sub-basins. This analysis is mainly confined to 11 fifth order sub basins. Morphometric indices like stream ordering, bifurcation ratio, stream length, drainage density, stream frequency, form factor, elongation ratio, circularity ratio, constant of channel maintenance, asymmetry factor, sin...

The eco-hydrological model SWAT (Soil and Water Assessment Tool) is a useful tool to simulate the effects of catchment processes and water management practices on the water cycle. For each catchment some model parameters (e.g. ground water delay time, ground water level) remain constant and therefore are used as constant values; other parameters such as soil types or land use are spatially vari...

Ciapus Sub Watershed is part of the Cisadane watershed which passes through 3 (three) sub-districts in Bogor Regency, namely Dramaga District, Ciomas and Tamansari District. From 2011 to 2020 housing construction Dramaga, increased. High enough rainfall continuous land changes will result water infiltration not functioning properly cause an increase surface runoff. Therefore, it necessary know ...

The U.S. Environmental Protection Agency (EPA) has been pressing for this type of approach since the promulgation of its Water Quality Trading Policy in 2003, the intent of which is “to encourage voluntary trading programs that facilitate implementation of Total Maximum Daily Loads (TMDLs), reduce the costs of compliance with Clean Water Act regulations, establish incentives for voluntary reduc...

Land use and land cover across 28 sub-basins within the Cosumnes Watershed, CA (1989 km) were correlated to nitrate-N and total suspended solids (TSS) loading between water years 1999 and 2001. The impact of human development on stream water quality was evident as both agricultural area and population density predicted TSS loading in a linear mixed effects model. In contrast to the TSS model, t...

Sungai Barito yang panjangnya sekitar 900 km merupakan sungai besar penting di Kalimantan. Penelitian dilakukan Sub Das Nagara, Marabahan dan Kuin. Berdasarkan perhitungan indeks keanekaragaman plankton pada Nagara untuk fitoplankton zooplankton termasuk dalam kategori perairan tidak tercemar, tercemar sedang berat, Kuin ringan sedang. Koefisien Saprobik β-Mesosaprobik, sedangkan nilai koefisie...
