Far reaching issues like that of wetlands can be effectively tended to with the assistance of GIS and remote detecting advances. GIS gathers and gives diverse parts of spatial data under one framework. Topographical information can be effectively investigated and worked with. This permits us to depict distinctive variations of advanced data in more target ways. The two variations of advanced spatial information, GIS and Remote Sensing go one next to the other to help in urban arranging.

The aim of this research is to model the landslide hazards and generate a landslide susceptible map by carrying out the risk assessment. Use of GIS in this study is to map out potentially hazardous new landslide areas, mudflows and developing landslide help to promote advance awareness of risks at hand and notify authorities (Oaego and Kuna 2006) with the tool to mitigate or engineer out the problem. Remote sensing allows for regional and extensive data collection at any given time saving cost and time with comparative analysis over time (Samanta et al. 2011 and
Monitoring the evolution of the coastline is an important task in several applications such as cartography and the environmental management of the entire coastal zone (Alesheikh et al., 2004). Erosion can happen under any conditions, but its rate tends to increase when waves are powerful and water levels are high, for instance during storms or in high winds. Remote Sensing and Geographic Information Systems GIS have become increasingly important tools for many applications, as these systems link information to precisely locations, and integrate information drawn from multiple sources (Shanti Pappu et al., 2010; Christoph Siart et al., 2008). These characteristics of water, vegetation and soil make the use of the images that contain visible and infrared bands widely used for coastline mapping. Examples of such images are: TM (Thematic Mapper) and ETM+ (Enhanced Thematic Mapper) imagery (Moore, 2000).
Therefore documenting basin characteristics using morphometric techniques, well-known since early nineteenth century, are very valuable. The studies by Horton (1945), Strahler (1957 and 1964), and Schumm (1956 and1963) are well known works in the field. Studies conducted by Dade (2001), Singh et al., (2005), Sreedevi et al., (2005), Mesa (2006), Rao et al., (2006), Sarkar and Gundekar (2007), Rudraiah et al., (2008), Angillieri (2008), Thomas et al., (2010) are some of the recent studies. The recent studies make use of the potentials of Geographic Information System (GIS) and Remote Sensing (RS) as the most popular and effective tools to investigate the river morphometry and basin characters. The present study examines the morphometric characteristics of Bharathapuzha River basin using GIS and RS
Lorber et al. (1984) used multiple parameters such as solar radiation and nutrients, to closely replicate field data. Wilson et al. (2005) used a logistic model of water hyacinth largely approximated on water temperature and nutrient concentration parameter calculated from the literature. These models are largely not ideal for small-scale water hyacinth populations experiencing numerous confounding factors.
Lammel et al (2010) conducted a tsunami evacuation study in the urban coastal areas for the city of Padang, in western Sumatra, Indonesia. Their research aimed to estimate the evacuation time, identify bottlenecks, and detect highly endangered areas of the study area. They used GIS to extract information from remotely sensed data, such as street data and building shape in order to classify them, based to their vulnerability. The researchers then combined the Digital Elevation Model (DEM) with their data to form a hazard analysis for the study area. From the hazard analysis, they produced tsunami inundation zone maps and found that the flow velocity of water from a tsunami is higher between buildings.
ABSTRACT In this study, Water Evaluation and Planning (WEAP) computer based water balance model was constructed and calibrated for the water Catchment at Benin City, Edo State "Nigeria using scenario approach in Water Evaluation and Planning Software (WEAP) for the period 2010 to 2060 and utilized to investigate the impacts of possible future demographic or policy changes on water demands on the catchment. Fifteen hypothetical scenarios representing plausible demographic changes, policies, population growth, water use rates, climate changes and cropping patterns were simulated. The model simulations show that the combined scenario of increase in population growth (IPGR) and increase in water use (IWU) produced the largest water demand for domestic and
