2. What is a drainage system ? In geomorphology, a drainage system is the pattern formed by the streams, rivers and lakes in a particular drainage basin. Drainage system

3. Problems arise with improper drainage system. Formation of stagnant pools providing places to the disease causing mosquitoes and other germs and they are very harmfull if they are located in living areas . They also pollute the Earth's surface and cause damage to soil which is the major cause for spreading diseases. Fig : Stagnant pool

4. 1. Flooding : The immediate effects of flooding include loss of human life, damage to property, destruction of crops and other plants, loss of livestock Poorly maintained drainage systems and poor waste management habits can adversely affect our environment in the following ways : Fig : Flooding

5. 2. Erosion: The absence of good drainage systems can cause erosion problems. This has been experienced in many areas of the world, where roads have been washed away and gullies created as a result of flooding. Fig : Erosion

6. 3. Diseases: Deterioration of health is another and major effect of flooding, due to the increase in waterborne diseases and unsanitary conditions. Stagnation of water occurs when water passages are blocked. This makes the people around such environments susceptible to infections from mosquitoes and other insects. We are exposed to numerous air and water borne diseases if we have our environments polluted with stagnant water. Fig : Mosquito biting a human Fig : Stagnant Water
