190stations. Cyclone related data are available with IMD. The above brief discussion clearlybrings out that process monitoring along the West Bengal coast is inadequate and sporadic.Although geomorphological maps are perhaps available, data on dynamic form monitoringlike berm, beach face and near shore bar mapping through tidal and seasonal cycles, data onnear shore bathymetric survey through such cycles, near shore wave period and wavedirection monitoring beyond the surf zone, estuarine form monitoring vis-à-vis estuarineprocess variability (like tide duration, magnitude, velocity, etc) on a daily, seasonal andlarger time scale are not available. Therefore any existing synthesis leading to a formprocess-materialinteraction model of different segments of West Bengal coast is speculativeand proposed engineering intervention to manage the shore line instability problems aretherefore not on required scientific base. The result is continued unpredictable shorelineinstability and failure of the engineering solutions to overcome the instability manifested incoastal erosion & accretion. The monitoring of ecosystem functioning in terms of biologicalprocesses that has a bearing on functioning form-process-material interaction model. Veryfew data on these aspects are at present available and consequently the contemplated ICZMPwill be prone to failure if such data are not collected and integrated with other data to arriveat an efficient ICZMP.391. The proposed two part M & E system will therefore include creation of an appropriate data base on relevant items through data acquisition fromsecondary sources, primary data generation in the laboratory and sites and primarysurvey or sample survey and will be tailored to be used as indicators forsuccess/failure in the coastal intervention programmmes. process monitoring of the coastal zones having open sea and/or estuary392. The above work plan by the PMU will provide for the development of essential toolsfor carrying out M & E of the proposed interventions in coastal areas of West Bengal as partof ICZMP, be it in the form of physical structures, biological shields and/or socio-economicdevelopment.393. Information on which evaluations are based thus could come from many sources, butmonitoring (observation) has a particularly important contribution in providing the basic datathat should underpin the evaluation. In this regard, indicators provide a useful tool to
