3. 1. Introduction:
Flood is a natural phenomenon that has been accepted by human societies as an
inevitable event and is considered one of the most costly natural disasters. But
the event, size and frequency of floods are due to several factors that vary
depending on the climatic, natural and geographical conditions of each region.
Due to the fact that floods and damages in most provinces of the country have
an increasing trend and cause death every year, Kapisa province in northeastern
Afghanistan has an area of 1908 square kilometers and a population density of
252 people per square kilometer in one of the most vulnerable province.

1. Rapid precipitation and lack of capacity of the place of descent.
2. Impenetrability of the ground and rapid melting of snow.
3. Lack of capacity and lack of proper design of river route and
floods.
4. Lack of use of flood dams and protective walls in flood-prone
areas Mountain collapse.
5. Lack of river dredging and accumulation of heavy and abnormal
sediments behind dams.
6. Damage to flood dams, dams and water tanks.

1. More desire for catchment areas.
2. Deforestation in catchment areas.
3. Lack of material in catchment areas.
4. Taking the sides of waterways by people.
5. Lack of rain gauges in most places.
6. Low awareness of people about floods.
7. Impacts of Climate Change and Drought.
6. 4. The amount of rainfall that has caused floods
According to the statistics of the Meteorological Department, the rainfall in the mentioned areas is between 10-40 mm
and according to the records, the flood is estimated at 30 mm, which shows about 1 hour. The rainfall is in the form of
urographic graphics. Villages in Hesa-e-Awal and Kuhband districts have been affected by valleys. Depending on the
severity of the flood in this area, the Rational Method has been used and the amount of water flow from the floods has
been received as shown in the table below.
