Flood Risk Management - Flood Resistance and Resilience
Published on by Zaheer Iqbal
Managing flood risk is easier rather stop it. Most importantly the concept of flood resistance and flood resilience proceed to the cost-effective solution to mitigate flood risk. This concept requires to an interaction of builders / architects and infrastructure designers behind flood defences and defence line.
Both, resistance and resilience flood risk measures are taken as risk mitigations under certain circumstances including strategic measures of local authorities and environment agency, as for example flood warning system, and actions to create options for infrastructure uses and locations.
The factors like insurance cover unlikely give any protection under the worst case scenario of flood risk to their properties and infrastructure, the only way to protect from the flood impacts through possible improvements as offered from flood risk planner and authorities in addition to improving possible measures for flood resistance and resilience.

Dear Zaheer,
The following two articles are also persuades the rainwater harvesting practices, which indirectly also help flooding prevention:

Hello Zaheer,
In case the following concept to be applied on the city environs and hinterlands, it would be a great help in mitigating the flooding, in addition to other benefts discussed in the article:

ABSTRACT
Out of 2.5% delicate amount of the freshwater, of the total water on the planet earth, only 1.2% of it is surface / other freshwater, available for use. And out of this 1.2%, only 0.49 of the surface freshwater is in the rivers, which could serve the life's needs on the planet, wherever not having access to freshwater in lakes.
Taking the maximum limit of 6-month time for the river residence time; if the water inflow into a river was not made-up, either via precipitations or ice and snow melts, it would dry-up, to the maximum, in the entire river bed, in 6 months.
In such drought situations, humans have no other choice, unless exploiting the precious underground freshwater, if within their reach and with a lot of energy input pumping it to the ground level, where adopted rainwater harvesting and storm water management measures are not in vogue. However, opting for saline water desalination measures would be considered, if other sources couldn't be utilized, since also desalination processes ask for a lot of energy and investment.
In many places worldwide, rainwater harvesting and runoff control measures could be adopted, for storing the rainwater for the use in the drought periods, to the extent that there are sample cases, such as - www.chooserain.com - , in which Mr. Larry Curran's premises is not connected to the city-water grid, but all live with the harvested rainwater, however, there is a lot of rainfall, in his place, but considering water conservation measures, it will also be practical in dry climates without too much rains. It will be also much advantageous catching the rainwater, in a place where it inherits potential energy, capable of free flowing to the end users. An example, in this regards is described on: http://www.atlaswaterharvesting.co.uk/, as well.
In fact, the logic behind the large dams’ construction, worldwide, has been the storing of the rainwater runoff, for the water use in the drought periods, and flash flood control, amongst other benefits, however, in the meantime losing a lot of water by seepage and evaporation and the environmental adverse consequences.
There are many measures for storing the rainwater, but in this article, a new concept; named as "Above-Ground Qanat" or a version thereof; the "Hooman-Mashallah Spring," - after the name of the late HOOMAN FARZAAD (1913 – 2005,) - is introduced for pilot trials worldwide, for free without any obligation thereof, like license fees or the like (the environmental know-how’s have to be freely available to all, anyway.)
In fact, while considering rainwater harvesting measures, where the harvested rainwater could reach the consumers; while inheriting potential energy with enough pressure; pieces of puzzle matched each other, forming the concept, as described; along with a complimentary wise comment thereon; on the linked-in discussions on: https://www.linkedin.com/grp/post/855897-5960720811722551298 ,obtained from Mr. Bill Harned (Experienced Developer/Project Manager, https://www.linkedin.com/pub/bill-harned/15/11a/773, Miami, Florida.)
In a nutshell, via building a few "Hooman-Mashallah Springs" ovrer an abandoned barren ravine / valley, at terraced elevations, one could convert its slope sides, into oasis cultivated green surfaces, providing wildlife guzzlers, as well and in the meantime maintaining a gravity power source of water to a community downhill. This concept really deserves a try. Any helping hands? It is free to apply; comments are most welcome.
It is assumed that via the application of this concept on the city environs / hinter lands, and the adaptation of the rainwater harvesting and storm-water management measures, in parallel, in urban areas; enough water could be maintained in many places. Yes we must catch the rainwater on time and on the spot, whenever and wherever it rains; preferably where inheriting potential energy, before running away from our reach; having in mind that the stored rainwater have to be kept in a manner to prevent smelling on aging.INTRODUCTION......
