Groundwater Visibility: The Missing Link.

Single-Point Visibility Constraint Minimum Link Paths in Simple Polygons

We address the following problem: Given a simple polygon $P$ with $n$ vertices and two points $s$ and $t$ inside it, find a minimum link path between them such that a given target point $q$ is visible from at least one point on the path. The method is based on partitioning a portion of $P$ into a number of faces of equal link distance from a source point. This partitioning is essentially a shor...

Integrate land and water use planning at the scale of the urban master plan

The survival of cities as living beings and their inhabitants depends on the supply of water. Numerous factors such as population growth, climate, drought, consumption pattern, amount of available water resources and utility network affect the equation of water supply and consumption. What has been less considered in the traditional planning process than ever before is the connection between la...

Estimation of groundwater level using a hybrid genetic algorithm-neural network

In this paper, we present an application of evolved neural networks using a real coded genetic algorithm for simulations of monthly groundwater levels in a coastal aquifer located in the Shabestar Plain, Iran. After initializing the model with groundwater elevations observed at a given time, the developed hybrid genetic algorithm-back propagation (GA-BP) should be able to reproduce groundwater ...
