Read the following passage and answer the following questions:

A team of researchers led by Professor Udit Bhatia, including Raviraj Dave and Srikrishnan Siva Subramanian, from the Indian Institute of Technology Gandhinagar (IITGN) has developed an integrated predictive model to accurately understand and assess the real magnitude of heavy rainfall-induced damages in road transport networks. This hazard model can help administrators identify the ‘hotspots’ which should be reinforced and protected to solve highway-flooding issues and minimise the socio-economic disruptions. The research team use satellite(A)/ imageries, ingeniously developed(B)/ landslide and debris flow models(C), and state-of-the-art flood predictions models to predict the occurrence time and geographical locations that have a high susceptibility to the simultaneous occurrence of flooding, landslides and debris flow events after heavy rainfall episodes.
