The hydrodynamic evolution of impulsively-heated coronal loops and their subsequent cooling can now be modeled with multi-wavelength imaging instruments in soft X-ray (SXR) and extreme ultraviolet (EUV) wavelengths. Using analytical approximations to the hydrodynamic evolution of the density n(s,t) and temperature T(s,t) of an impulsively-heated loop (as a function of the loop length coordinate s and time t) we show an example how lightcurves observed with HINODE/XRT, EIS, GOES, and STEREO/EUVI can be modeled with a forward-fitting method in order to infer the maximum heating rate, the heating duration, and the cooling time of a heated loop during a small B1-class flare on 2007 February 1, previously analyzed by Warren et al. (2007).
