A modelling and analysis approach for evaluating alternatives to reduce impacts of riverine flooding in Eastern North Carolina USA
The town of Windsor along with numerous other small communities in Eastern N.C. suffered tremendous impacts as a result of riverine flooding associated with several recent hurricanes. Several major interstate highways were overtopped making them impassable and paralysing emergency services. In addition, numerous secondary roads were flooded or completely washed out. Small communities like the town of Windsor do not have the capacity or technical staff to conduct modelling or analyses necessary to identify factors suspected of exacerbating the flooding or to identify or evaluate potential flood mitigation measures. A team of NC State University engineers conducted extensive geospatial, hydrologic and hydraulic modelling in order to assist the town identify potential steps for mitigating the flooding of future severe rainfall events. Several potential actions to improve infrastructure and to mitigate flooding were identified and modelled.

Improving resilience of water supply to flooding in Cagayan de Oro, Philippines
The “Ridge to Coast, Rain to Tap” (R2CR2T) project aims to reduce flood vulnerability and improve the resilience of water supply in Cagayan de Oro (CDO). The project adopts an integrated approach, aimed both directly at the water supply infrastructure and at a systemic level in the river basin. Through investments and technical assistance, the project improves the operations of the CDO Water District. Water supply coverage and sanitation services are expanded with 7,000 previously unserved households, primarily victims of the severe 2011 Sendong floods. In the upstream river basin, pilot reforestation interventions are implemented in partnership with local Indigenous Peoples (IP) communities to demonstrate sustainable ways for addressing the causes of flooding. The project contributes to an enabling environment in which many stakeholders in CDO cooperate towards flood risk reduction. R2CR2Tis a PPP, co-financed by the Sustainable Water Fund of MOFA Netherlands.

Governance for improved basin management
Ziway-Shalla sub-basin (‘Ziway basin’) is one of the four lake sub-basins in the Ethiopian Rift Valley. Lake Ziway is the only fresh water lake in the Rift Valley. Water imbalance is currently posing a threat to the basin. The volume of water drawn from the Lake Ziway for irrigation purposes increased in the last two decades, with declining water quantity and deteriorating water quality as a result. With the establishment of the Rift Valley Lakes Basin Authority (RVLBA) as an autonomous government body, the legal and institutional framework for a balanced water use and sustainable management of the basin resources were put in place. In terms of implementation, however, the momentum and the capacities for the execution of the authority mandate are lacking. As a young organisation, RVLBA is looking to improve its resources and capacities for water allocation and sharing, and for integrated lake basin management.

Clay ripener: Beneficial use of dredged sediment to create clay that fulfils the need for Dutch dike reinforcement
The clay ripener puts sustainable use of resources into practice by re-using dredged sediment from harbour and navigation channels, as well as river floodplains, to create clay that meets the criteria for clay for dike reinforcement. This is a win-win situation: sediment is removed from the nearby estuary, improving water quality. The sediment is used to reinforce the dike, thereby improving flood protection. And last but not least, it fits perfectly in the philosophy of the circular economy.

Groundwater development and management at micro-watershed level- a case study from Vellore district, Tamil Nadu India
In arid and semi-arid climatic zones of hard rock terrain due to lack of available surface water, ground water is considered a precious renewable resource. The study comprises of Kaniyambadi block of 245 Sq.km area covering 40 microwatersheds of Naganadi Watershed with an average annual rainfall of 1021mm supporting a population of around 50,000. Even though the catchments have good groundwater potential, the management practices are lacking and result in water deficiency in 62 villages. The Geospatial technique developed mainly on the basis of Geological and geomorphological factors using GIS and RS tools. The plan prepared by this technique has been able to revive/accelerate the water conservation and its sustainability. The information derived from various thematic and secondary data sources are analysed in detail at micro level and an action plan is prepared by overlay analysis. For implementation in the field, the action plan is submitted to district administration and it has been implemented under MGNREGA for execution by way of community involvement. The Project has provided employment to locals, especially rural women through existing Government Schemes. It ensures Environment Sustainability, engaging communities and raising awareness on groundwater conservation initiatives.
