The first step in developing an interactive map linked to relevant data that you want to represent is to select the coordinate system with which you want to work.The tip is if you are working in a global scale use the global coordinate systems. If you are working within a country use the local coordinate systems. If the scale of you work is within the district/state then use cadastral maps. A single point can be represented by x and y axis of your paper,height and width of your room or even the global coordinate systems. ...More

Selection of Conceptual Hydrologic Models for Estimating Runoff from Arid Watersheds(NEW)
The selection of ideal conceptual hydrologic model for prediction of surface runoff from any type of watershed is useful for the estimation of future hydrologic conditions of the basin.The predicted runoff is also important for design of hydraulic structure,preparation of watershed management plans ,disaster management etc. related activities.The future runoff will give an idea of future uncertainties that may trouble the watershed and its inhabitants.The hydrologic models which follows the basic physical laws of water balance to estimate the desired output cannot exactly estimate the runoff.There will be some differences with the actual situation and the predicted one.The deviations between the two is allowable but to a certain extent.There are many factors for this deviation.Some models are suitable for some specific types of watersheds.The availability of required dataset is also another important issue.The equalizing constants that are used to linearize interrelationships are also a factor for the error produced by the hydrologic model.That is why selection of a suitable hydrologic model which can estimate at a desired accuracy under the restrictions imposed by the study watershed and dataset availability is important for successful execution of projects involving runoff predictions.The present study tries to select a suitable hydrologic model based on the related factors and decision making algorithms for predicting surface runoff from an arid watershed.The decision making algorithms are popular for their impartial and scientific decision making based on historical,social and expert inputs.The advancements of such algorithms can be utilized to select an ideal hydrologic model which can minimize the error between the predicted and actual output.

The Domestic Energy Management Tool can be utilized for selection of a plan of energy use by the domestic consumers implementing which will yield maximum saving of energy possible after satisfying the requirements and using loads with minimum pollution potential.It is developed for the household user and it tries to provide a platform where different appliances can be rated for importance with respect to conservation of energy,pollution potential and necessity of utilization.....More
Analytical Hierarchy Process Assisted Water Quality Index Calculator(AHP WQI)(NEW)
A new calculator for calculation of Water Quality Index(WQI) by the Analytical Hierarchy Process(AHP) which determines the weightage of importance of each parameter over the other with the help of specific scale of importance and determines the WQI in a more relative,justified and cognitive manner. Based on the importance of the parameters, the weightage of each parameter for the WQI is determined. AHP is an example of Multi-Criteria Decision Making which is widely utilized nowaday for logical decision making....More
Although the concept of water security is relatively new, but such parameters can prevent wastage of water which is important for the impending days of water scarcity.Water security defines the availability of a certain amount of water which will be accessible and utilizable even under massive scales of uncertainty in the climate and total failure of conservation efforts.The water security of any region is directly proportional to the minimum water available to sustain the demand.
To find the loss of pressure or flow within a pipeline we can use the concept of graph theory and Mason Gain Formula where gain can be equivalent to flow resistance.Kirchoff's Current and Voltage Law can also be used to solve pipe line problems where Voltage can be replaced by Tanks/Reservoirs,resistance by friction loss and current with flow of water.The capacitance can be compared to surge tanks and inductance may be replaced by the eddy flows which often causes the hammering.Such methods can easily determine the value of losses within a pipeline if flow and potential is known and necessary scale corrections are applied.
