Engineered systems known as flood control structures are intended to lower the danger of flooding and shield ecosystems, infrastructure, and communities from flood damage. Levees, embankments, flood barriers, and spillways are some of the structures that assist regulate water flow and stop overflow in places that are susceptible. Furthermore, floodgates, retention basins, and diversion channels control surplus water by securely rerouting it during peak occurrences. By providing these solutions, flood management structures can protect areas from the effects of storm surges, river overflow, and excessive rainfall while promoting environmentally friendly practices and sustainable water resource management.

Embankments:

An embankment is a raised structure made of earth or stones that serves a variety of purposes. With the collaboration with CPI Division of IWM and BWDB as the client, a design for Embankment & Protection Work around Dacope Upazila was provided for the Feasibility Study for Restoration and Development of Water Resources Management System of Polder 31 under Dacope Upazila in Khulna District. Same was proposed around Kutubdia Island (Polder-71) and around Matarbari Island (Polder-70) around Sandwip Island. A typical design section for embankment construction as a flood management structure is given below.

Dams:
Multi-purpose dams are a structural measure used to control flooding. A dam is walled construction, known as the water retention structure, keeps water out while permitting a certain amount to flow downstream. Depending on their intended use, the topography, and the resources available for building, they are made of different materials and designs. With the collaboration with FRM Division of IWM and BWDB as the client, Design for Earthen dams were proposed to be constructed in Govania, Ambaria, Kumira and Joramtol under the project of Feasibility Study for Conservation and Use of Rainwater Through Construction of Environment Friendly Water Reservoir at Khoia Chhara and Govania Chhara of Mirsharai Upazila and Kumira Chhara of Sitakunda Upazila Under Chattogram District.

A design for an earthen dam along with spillway, intake tower and pedestrian bridge at  Govania Chhara in Mirsharai Upazila was provided for the Chattagram District's Feasibility Study for Conservation and Use of Rainwater in collaboration with the FRM Division of IWM and BWDB as the client. The same idea was submitted for Sitakunda Upazila's Joramtol Khal and Kumira Chhara. A cross dam was also proposed on the Govania Chhara Reservior, An earthen dam, also known as an earthfill dam, is a kind of dam that is mostly made of natural materials like rock, gravel, sand, clay, or soil. Since building materials are readily available and construction methods are generally straightforward, earthen dams are among the oldest and most popular types of dams. It blends well with the natural landscape. The proposed earthen dams in those areas will retain water, guarantee a consistent supply, and enable precise control over water discharge, guaranteeing effective distribution to industries, municipalities, and irrigation systems.

Designing an irrigation system involves carefulness to guarantee effective water distribution to crops while preserving resources. We consider and focus on every agronomic and environmental factor while building the layout, choosing appropriate technologies, and evaluating requirements for an irrigation system. An irrigation system designing requires perfection to the core. It consists of designing the canals, dykes, check structures, regulators, syphon, aqueducts etc. Collaborating with IGW division, DGN unit worked in BIP (Barishal Irrigation Project), KIP (Kurigram Irrigation Project), PIRDP (Pabna Irrigation and Rural Development project) projects.
