Century-long studies on the impacts of forest management in North America suggest sediment can cause major reduction on stream water quality. Soil erosion patterns in forest watersheds are patchy and heterogeneous. Therefore, patterns of soil erosion are difficult to model and predict. The objective of this study is to develop a user-friendly management tool for land managers to design forest m...

Increasing population growth worldwide is putting increasing pressure on water resources. In arid and semi area pressure goes to groundwater. Keeping in view havoc capability of remote sensing and GIS, a study for the integrated groundwater development has been under taken in part of Lalitpur district, Uttar Pradesh. The Satellite data of IRS -IC and ID have been used to prepare the hydrogeomor...

Climatic variability, unplanned land use pattern and encroachment into the flood plain are affecting the hydrology of Bagmati river basin of Nepal. In this study, methodology to improve present flood management system with non-structural countermeasures has been elaborated. Study of hydrological condition, basin scale rainfall runoff modeling and inundation analysis is helpful to prepare commun...

One characteristic of a Geographic Information System (GIS) is that it addresses the necessity to handle a large amount of data at multiple scales. Lands span over an area greater than 15 million km all over the globe and information types are highly variable. In addition, multi-scale analyses involve both spatial and temporal integration of datasets deriving from different sources. The current...

Soil Conservation Service (SCS) and overland flow models have been used for runoff modeling over major land mass of India. Remote sensing derived daily rainfall data (Climate Prediction Centre), high temporal NDVI data (SPOT VGT), DEM (GTOPO30) and soil texture maps were used as input for the runoff modeling. SCS model setup was done in GIS (Arc GIS) environment. In general the reported and mod...

Flood plains and the area near to the rivers channels, because of their special circumstances such as fertility and water resources are appropriate situations for the social and agricultural activities, but due to morphological characteristics usually, these area are affected by different flood hazards. However, in these areas, determination of flood zone and its height and also detecting prope...

Deforestation in the Serayu watershed, Central Java province, Indonesia for agriculture and other uses leaves only 0.73% of vegetation. It has triggered a number problems such as soil loss (erosion), landslides, floods sedimentation downstream. Environmental damage control needs to be applied through appropriate conservation programs. This study aims understand distribution erosion effectivenes...

Present work is aimed at assessing Water Quality Index (WQI) for groundwater of Upper Pincha Basin, Chittoor District, Andhra Pradesh. This has been carried out by collecting groundwater samples and subjecting them to comprehensive physico-chemical analysis. Results obtained were compared with standard values recommended by WHO for drinking and public health. For computing WQI, eleven parameter...

Among the poor in developing countries, up to 20% of an infant's life experience may include diarrhea. This problem is spatially related to the lack of potable water at different sites. This project used risk analysis (RA) methods and geographic information system (GIS) technologies to evaluate the health impact of water source. Maps of Imo State, Nigeria were converted into digital form using ...

This paper reviews three readily available cartographical databases (DBs), the Digital Chart of the World (DCW), the World Vector Shoreline (WVS) and 30 Arc-Second DCW Digital Elevation Models (DEM) all originating from the US Defense Mapping Agency (DMA). These are presumed strong candidates as cartographical data sources for strategic needs at several Consultative Group of International Agric...
