GOOD QUESTION,

THIS STATE RECEIVES AN AVERAGE OF 300 mm OF RAINFALL IN A YEAR, BUT IN THE LAST FEW DAYS ALONE, CERTAIN PARTS OF THE STATE HAVE RECEIVED OVER 500 mm OF RAINFALL, WHICH EQUALS TO TWO YEARS WORTH OF RAIN IN TWO DAYS.

THE SOIL CONTENT HAS A HIGH GYPSUM COMPOSITION, WHICH DOES NOT ALLOW RAIN WATER TO SEEP INTO THE EARTH EASILY, THERE BY INCREASING THE SURFACE RUNOFF MANY FOLDS.

RESULT - FLASH FLOODS IN THE DESERT.

Most answers are good but bottom line for flash food is:

1. Too much water all of a sudden and no drainage.

2. Too much water putting excess pressure on dam, beyond its capacity.

3. Old dams just breaking up.

4. Lot of time debie accumulate in a narrow part of the river or an innocent looking creak, water can build up pressure on this temporary dam, but it always reaches a point when the dam breaks.

5. There are animals that build dams one such animal is Beaver, there are Beaver dams all over the world. When these dam cause enough water to collect, they cannot take the pressure, they break and you do not need any rain to do this, melting snow just slow accumulation over long period or rain far far away, may cause this to happen.

6. See if you can come up with few causes, now that you have seen some of the causes.

The definition of "FLASH FOOD" is just that, flood occurring in a flash(sudden), water does not stay too long, it just destroys every thing in its path. It is like a wall of water advancing at high speed, destruction is due to presser exerted by this wall of water.

Rajasthan is mostly a desert. The land is parched and dry. It doesn't normally rain hard there. So the soil couldn't adjust to the amount of rain the place received recently. So a flash flood occured.

Small amounts of rain fall in a place is the easiest way for a flash flood to happen. The ground becomes parched and unable to absorb watter quickly. The rain falls heavy and just sits on the ground. The low areas flood and there you have it, flash flood.

Flash floods are caused by sudden heavy rains in higher elevations (desert mountains for example). The water rushes to lower levels picking up momentum to strike miles away from where the rain was falling. They are called flash floods because they have little to no warning to the area they hit.

It can happen when the Govt is not responsible and there are not enuf educated or Geo / Enviorment specialist team within Govt departments, unplanned, uninformed opening of Dams could make this happen too, Indian Govt needs to involve a team of speicalist from private sectors in situations like this rather then depending on DUMB internal team!

It's because the ground is dry and baked hard, so if it rains heavily, all the water stays on the surface because the ground is too hard to absorb the water.

you can call it environmental disaster. These are all the signs of changing behaviour patterns of mother nature (earth), towards the indiscrimnate use of crude oil out of its womb and of course emission of burnt oil into atmosphere to enoromous level.
Something is going to give in.
Surprises like Tsunami / Earthquakes, drastic environmental changes, re-organisation of deserts or sea and land are likely to be on the cards, as two mighty economies like China and India start getting momentum of development.
