One of KPA Engineer’s recent contracts involved performing drainage assessment studies for several watersheds. The study area included 73 square miles of drainage area, parts of which were located in the City of Temple, Texas, extraterritorial areas, and within the County of Bell, Texas. ...
From June 2008 to March 2009 the PEI Soil & Crop Improvement Association initiated and administered a unique project that focused on riparian health assessments for PEI. The project was unique in that it provided training to members of watershed groups across the Island so that they could develop the technological capacity to conduct riparian health ...
A 2001 water analysis measured Powers Lake as "hyper-eutrophic" and the watershed assessment specified the lake received an annual phosphorus load of 11,564 pounds. ...
Presently, integrated watershed management is receiving worldwide recognition as an effective model for watershed planning. A watershed is considered the basic geographical unit for developing any plan by integrating various social, economic, and policy factors with modern science. ...
The restoration of watershed health can be influenced by ecological, technical and socio-economic factors. The paper presents a conceptual framework and typology to assess watershed ecological restoration based on the properties and processes of sustainable watershed development. ...
A simple approach was developed in this research to assess the NLC of paddy soils in the southern Taihu Lake watershed. Paddy soils were classified into four types (Submergenic, Illuvium, Gleyed, and Percogenic) and 28 soil samples representing all four types were collected from across the region. The NLC values of the paddy soils were assessed ...
The present deficit of 3.92 MLD (2014) may amplify to 59.01 MLD in 2051. Resource assessment in the related watersheds namely, Ashwani, Nauti, Giri and Pabbar accomplished using remote sensing techniques and geographic information system (GIS) based Arc-SWAT hydrological model. Average annual precipitation in all watersheds for 26 years ...
Here, a water quality assessment model (WQAM) is developed by non-linear regression as an alternative to physical watershed modeling in South Korea. ...
In practice, this linkage typically relies upon relatively limited chemical occurrence data loosely coupled with individual effects, and population or community level assessments. Increased discriminatory power may be gained by approaching watershed level assessment in a more holistic manner drawing from a number of disciplines that target ...
This study performed a flood risk assessment using one of the multi criteria decision-making methods to identify the small stream basins with high risk of flooding and to determine the optimal small stream restoration measures by priority ranking for flood risk. The 12 representative factors for the flood risk assessment were carefully selected and constructed ...
The impact of waterborne micro-organisms (potentially pathogenic) on public health may be exacerbated by the combined effects of climate and land use change. We used watershed modeling to assess the potential effects of climate change and future land management scenarios on microbial water quality in the Pigg River watershed, located in ...
Understanding impacts of changes in climate and land use on ecohydrologic processes in a watershed is vital to sustaining water resources for multiple uses. This study completes a continental and regional scale assessment using statistical and simulation modeling to investigate ecohydrologic impacts within watershed systems. ...
LID did reduce risk but only when implemented at high intensities within the urban watersheds. The structure of the BN‐RRM also provides a framework for water quality‐ and quantity‐related endpoints within this and other watersheds. ...
Watershed modeling was conducted in 20 large, U.S. watersheds to characterize the sensitivity of streamflow, nutrient (nitrogen and phosphorus), and sediment loading to a range of plausible mid-21st century climate change and urban development scenarios. ...
These efforts include comprehensive planning, data gathering and storage, Geographical Information System (GIS), watershed assessment, modeling, and providing assistance with communicating the watershed management approach to the regulatory agencies and the public. Result LimnoTech developed 16 watershed characterization reports ...
Resource management agencies in the USA are expanding the use of tools for the assessment of ecosystem function in water quality programs to control NPS pollution to meet US Clean Water Act objectives. ...
From 2008 to 2013, a series of studies supported by the Canadian Water Network were conducted in Canadian watersheds in an effort to improve methods to assess cumulative effects. These studies fit under a common framework for watershed cumulative effects assessment (CEA). This paper presents an introduction to the Special ...
This paper is the second in a two‐part series assessing the accumulated state of the transboundary Yukon River basin in northern Canada and the USA. ...
Biomarkers can be used as tools to help determine ecological exposure in watershed assessments. In the present study, metallothionein and fixed wavelength bile fluorescence for two‐, four‐, and five‐ring hydrocarbons were used as biomarkers of exposure in largemouth bass (Micropterus salmoides) in the Reedy River watershed located in South ...
